• motor neurone

Multiple Choice

transmit impuls from receptor to central nervous system

• sensory neurone

• motor neurone

Multiple Choice

Dendrite has function

• Control activities in nervous system

• receives impulses

Multiple Choice

Myelin sheeth has function

• slower the speed of signal

• increase the speed of signal

Multiple Choice

Reflex arc doesn't need central nervous system to process the information

• true

• false

Multiple Choice

What is receptor cell ?

• convert stimulus into energy

• Transmit impuls to motor

Multiple Choice

Stimulus is decided and will be convert to responds depend on

• location of the receptor cell

• type of receptor cell

Multiple Choice

What is resting potential ?

• when the inside of the cell is more negative than outside

• when the inside of the cell is more positive than outside

Multiple Choice

In stage of resting potential, nervous system

• Still give the respond on stimulus

• Can't respond the stimulus until they reach threshold

Multiple Choice

How much the voltage is the threshold to action which will be responded ?

• -70mV

• -55mV

Multiple Choice

When NA+ channel open and Na+ are flowing inside the cell and make the condition of the cell is more positive than outside

• repolarization

• Depolarization
